- HEDDLE BAR POST Filed April 27, 1938 Patented Dec. 13, 1938 UNITEDSTATES PATENT OFFICE HEDDLE BAR POST Application April 27, 1938, SerialNo; 204,643

7 Claims.

This invention relates to loom harness frames and particularly toharness frames in which steel heddles are mounted. It is customary toprovide steel rods or heddle bars to support the steel heddles in suchframes, and it is customary to secure the ends of these heddle bars inthe side pieces of the harness frames. In Wide frames, however, it isalso-desirable to attach the heddle bars to the top and bottom membersof the harness frame at one or more intermediate points, and for thispurpose heddle bar posts have been provided.

It is the general object of our invention to 1mprove the construction ofsuch heddle bar posts as heretofore used, and to provide a new type ofpost which is economical to manufacture and which is convenient andreliable when in use, and relative to which a heddle bar may beconveniently attachedor removed.

Our inventionfurther relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claims.

A preferred form of the invention is shown in the drawing, in which Fig.1 is a front elevation of .a portion of a harness frame having ourinvention applied thereto;

Fig. 2 is a blank from which the outer casing of our improved heddle barpost may be conveniently formed;

Fig. 3 is a front elevation of the casing formed from the blank shown inFig. 2-;

Fig. 4 is a side elevation of the casing shown in Fig. 3;

Fig. 5 shows a blank from which a threaded stud may be convenientlyformed;

Fig. 6 is a front view of a stud formed from the blank shown in Fig. 5,but before the threading operation is performed thereon;

Fig. 7 is a side elevation of the threaded stud;

Fig. 8 is a side elevation of the complete heddle bar post;

Figs. 9 and 10 are side and end views of a spring used in our improvedpost;

Fig. 11 is a side elevation of the post in use, with the heddle barshown in section; and

Fig. 12 is a front elevation, looking in the direction of the arrow 12in Fig. 11.

Referring to Fig. 1, we have shown parts of a harness frame including abottom member I5, end pieces IE, a plurality of steel heddles I1, and aheddle bar l8, the ends of said bar being attached tothe harness frameby any usual securing de- Vice, not shown.

Our; improved heddle bar post P is shown in operative positionin Fig. land connects the heddle bar If! at an intermediate point with thebottomframe member 15.

It will be understood that a second heddle bar I is. provided for theupper ends of the heddles H and that a similar heddle bar post securesthe upperheddle bar to the top member of the harness frame.

Our improved heddle bar post is shown in side '10 elevation in Fig. 8and comprises a threaded stud 20, a casing 2! slidable on the stud. aspring 22, and a pin 23. The casing Zl'may be conveniently made fromsheet material by providing a'blank B as shown in Fig. 2, from which thecasing 2|.may be formed by bending or folding operations. The casing 2i,when complete, presents. the; appearance shown in Figs. 3 and 4, with anopening 2'5 in its forward edge portion and with offset recesses 26inits side portions to receive the-lower edge of a heddle bar [8. Slottedopenings 21 are provided for the ends of the pin 23, when the parts areassembled as shown in Fig. 8. The lug or projection 28 at the top of theblank is bent downward to close the upper end of the casing and toprovide a seat for the upper end of the spring 22.

The threaded stud 20 may be machined from a rectangular steel rod but ispreferably formed from sheet metal by providing a blank B as shown inFig. 5, the sides of which are then folded together to produce thestructure shown in Fig. 6. This part is then threaded to provide thefinished stud 20 shown in Figs. '7 and 8. The stud 20 has an opening 30in its front edge, together .with an upwardly offset recess 3| toreceive the upper edge of the heddle bar l8.

The spring 22 may be of any usual form but is preferably a specialspring as shown in Figs. 9 and 10, comprising a series of reverse loopsin a, vertical plane, together with transverse loops at its two ends.

In assembling our improved heddle bar post, we place the spring 22 inthe closed end of the easing 2|, then slide the casing 2| over the stud20, and insert the pin 23 through the slots 21 and through an opening 33in the stud 20, the pin being preferably a drive fit in the opening 33.

When a heddle bar is to be inserted in the post P, the operatordepresses the casing 2| by pushing on the outer end thereof, thusbringing the openings 25 and 30 into alignment, so that the heddle barl8 can be freely inserted from the side. The casing is then released andslides upward to the position shown in Figs. 8, 11 and gas 12, thusfirmly gripping the heddle bar 18 and efiectively preventing lateraldisplacement thereof.

The heddle bar may be readily removed, however, by pressing downward onthe casingZl in the direction of the arrow a in Figs 11. A particularadvantage of my improved post lies in the fact that the spring 22 isentirely enclosed within the upper part of the casing 2| and is thusfully protected from injury or accumulation of dirt or lint.

Having thus described our invention and the advantages thereof, we donot wish to be limited to the details herein disclosed, otherwise thanas set forth in the claims, but what we claim is:

1. A heddle bar post comprising a stud, a casing extending beyond theouter end of said stud and having a portion to underly a heddle bar, aspring mounted between the outer ends of said stud and casing, and meansto limit outward movement of said casing relative to said stud.

2. A heddle bar post comprising a stud having a side opening to receivea heddle bar and having a part overlying said bar, a member slidable onsaid stud and having a part underlying said bar and a part extendingbeyond the outer end of said stud, a spring interposed between the outerends of said stud and sliding member and operative to move said memberoutward to lock a heddle bar in position, and means to limit outwardmovement of said sliding member relative to said stud.

3. A heddle bar post comprising a stud having a side opening to receivea heddle bar, a casing slidable on said stud and having a correspondingside opening, said casing extending beyond said stud and being closed atits outer end, a spring interposed between said closed casing end andthe outer end of the stud, and means to slidably secure said casing onsaid stud.

4. A heddle bar post comprising a stud having slidable on said stud andhaving a side opening with an inner end recess to receive the under edgeof said bar and having an end portion extending beyond the end of saidstud, a spring interposed between'the outer ends of said stud and casingand efiective to move said casing to locking position, and means tolimit sliding movement of said casing relative to said stud.

6. A heddle bar post comprising a stud having a side opening with anouter end recess to receive the upper edge of a heddle bar, a casingslidable on said stud and having a side opening with an inner end recessto receive the under edge of said bar, said openings being alignable topermit insertion or removal of a heddle bar and said casing having anend portion extending beyond the end of said stud, a spring interposedbetween'the outer ends of said stud and casing and effective to movesaid casing to locking position, and means to limit sliding movement ofsaid casing relative to said stud.

'7. A heddle bar post comprising a folded sheet metal stud, a foldedsheet metal casing extending beyond the outer end of said stud andhaving a portion to underly a heddle bar, a spring mounted between theouter ends of said stud and casing, and means to limit outward movementof said casing relative to said stud.
